Abstract: In an example implementation, a grounding structure includes a perimeter ground line around the perimeter of a printhead die, and having north, south, east, and west segments. The structure includes an inter-slot ground line extending from the north segment to the south segment between two fluid slots, and an alternative ground line extending from the east segment to the west segment and intersecting the inter-slot ground line in a connection area near ends of the fluid slots.

Abstract: A memory circuit for a print component including a plurality of I/O pads, including an analog pad, to connect to a plurality of signal paths which communicate operating signals to the print component. The memory circuit includes a controllable selector connected in line with one of the signal paths via the I/O pads, the selector controllable to disconnect the corresponding signal path to the print component, and a memory component to store memory values associated with the print component. A control circuit, in response to a sequence of operating signals received by the I/O pads representing a memory read, to operate the controllable selector to disconnect the signal path to the print component to block the memory read of the print component, and provide an analog signal to the analog pad to provide an analog electrical value at the analog pad representing stored memory values selected by the memory read.

Abstract: An integrated circuit to drive a plurality of fluid actuation devices includes an ID line, a fire line, a discharge path, a memory element, and a latch. The memory element is electrically coupled to the fire line and the discharge path. The latch disables the discharge path in response to a first logic level on the ID line and enables the discharge path in response to a second logic level on the ID line.

Abstract: In some examples, a circuit includes a data line, an input line, a first memory element, and a decoder to receive an address and to enable the first memory element for access in response to the address. The selector is responsive to the data line to select the first memory element, where the selector is to select the first memory element responsive to the data line having a first value, and where the data line is to communicate data of a second memory element in response to the second memory element being enabled for access. The input line is to communicate data of the first memory element in response to the first memory element being selected by the selector.

Abstract: The present subject matter relates to disposing memory banks and select register. In an example implementation, a plurality of memory banks is arranged to form a group of memory banks. Each memory bank includes a plurality of memory units. At least one select register generates a select signal to access the memory units in the plurality of memory banks. The at least one select register is disposed at an end of the group of memory banks.
